GFCI
Also called: Ground Fault Circuit Interrupter
A GFCI (Ground Fault Circuit Interrupter) is an electrical receptacle or breaker that shuts off power within milliseconds when it detects a ground fault — current escaping from the hot wire to ground. The National Electrical Code requires GFCI protection on all kitchen, bathroom, garage, outdoor, and basement outlets in renovated spaces.
Why this matters for renovation projects
GFCI shows up on permits, contracts, or estimates that Renology covers across LA, San Diego, San Francisco, Seattle, Portland, and Denver. Most homeowners encounter the term once a project is already mid-flight, when there is no time to learn its mechanics without slowing the contractor. Knowing what it means before signing the contract is the difference between a clean project and an avoidable surprise. For how Renology calibrates cost ranges against permit valuations and contractor invoices, see the methodology.
